Quinoxaline, 2-chloro-, 1-oxide, also known as 2-Chloroquinoxaline 1-oxide, is a chemical compound with the molecular formula C8H5ClN2O. It is a derivative of quinoxaline, a fused bicyclic compound consisting of a benzene ring fused to a diazine ring. The 2-chloro substitution introduces a chlorine atom at the 2nd position of the quinoxaline ring, while the 1-oxide functional group is attached to the nitrogen atom at the 1st position. Quinoxaline, 2-chloro-, 1-oxide is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and reactivity. It is typically synthesized through the oxidation of 2-chloroquinoxaline with an appropriate oxidizing agent. The compound is considered hazardous and requires proper handling and storage to ensure safety.

5227-57-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5227-57-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,2 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5227-57:
(6*5)+(5*2)+(4*2)+(3*7)+(2*5)+(1*7)=86
86 % 10 = 6
So 5227-57-6 is a valid CAS Registry Number.

First synthesis of 2-phosphonylated quinoxaline 1,4-dioxides: An extension to the Beirut reaction

Dahbi, Samir,Methnani, Ebtissem,Bisseret, Philippe

, p. 5516 - 5520 (2010)

An extension of the Beirut reaction for the preparation of the first members of the 2-phosphonylated quinoxaline 1,4-dioxide series is described. Contrary to their carboxylated equivalents, preparation of these new compounds could not be achieved under basic conditions but required the use of powdered molecular sieves. Good and reproducible yields were obtained only when the initial suspension in THF was transformed into a pasty film by slow evaporation of ca. 90% of the initial solvent volume.
